Event Description
|
This report is being filed after the review of the following journal article: gomesa, c.Et al (2015), monopolar-probe monitoring during spinal surgery with expandable prosthetic ribs, orthopaedics & traumatology: surgery & research volume 101(4),june 2015,pages s193-s197 (france).The primary objective of this study was to assess the reliability of our technique for brachial plexus monitoring by comparing the stability of neurogenic mixed evoked potentials (nmeps) at the upper and lower limbs with patients during vertical expandable prosthetic titanium rib (veptr) procedures.Where injuries to the spinal cord and brachial plexus have been reported after veptr implantation in 2 and 5% of patients, respectively.Between january 1, 2012 and september 1, 2014, twelve vertical expandable prosthetic titanium rib (veptr) procedures performed in 6 patients (3 male 3 female) with a mean age of 7.2 years (range, 6.1¿7.9 years) at first veptr implantation were monitored using a monopolar stimulating probe and were included in the study.The keypoint®4.2 system(medtronic,minneapolis, mn, usa), a commercially available intraoperative monitoring (iom) device was used.The following complications were reported as follows: adverse event in the right upper limb during the distraction procedure in 1 patient, with a good outcome.Neurogenic mixed evoked potential (nmep) amplitude dropped sharply then recovered totally after an alert by the neurophysiologist and promoted the surgeon to lift the distraction applied by the vertical expandable prosthetic titanium rib.This report is for an unknown vertical expandable prosthetic titanium rib (veptr).This is report 1 of 1 for 1 for (b)(4).
